Check Digit Verification of cas no

The CAS Registry Mumber 203631-76-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,6,3 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 203631-76:
(8*2)+(7*0)+(6*3)+(5*6)+(4*3)+(3*1)+(2*7)+(1*6)=99
99 % 10 = 9
So 203631-76-9 is a valid CAS Registry Number.

Efficient formation of aromatic thiols from thiomethylated precursors

Pinchart, Alain,Dallaire, Carol,Van Bierbeek, Alain,Gingras, Marc

, p. 5479 - 5482 (2007/10/03)

As a model study, a series of linear and branched p-phenylene and m- phenylene sulfides, functionalized by a thiomethyl group, were deprotected to thiols while using various alkyl thiolates at 160°C in DMF. Many complex aromatic thiols were obtained in al

Synthesis of p-phenylene sulfide molecular asterisks

Gingras, Marc,Pinchart, Alain,Dallaire, Carol

, p. 3149 - 3151 (2007/10/03)

'Megastars' with aromatic central cores, some of which fluoresce, were synthesized by the efficient connection of the side arms to the core by using the MacNicol reaction. Depending on the length of the side arm precursor, second-, third- (depicted), or f
